I am posting in search of some help. I am currently helping a friend work on his 86 brat. Due to other issues and finding a new carb off a EA82 , we are replacing the intake and carb with that from a EA82. We removed the intake with no problem but the EGR piping that goes from the top of the block into the intake will not come unscrewed from the block. We have tried using a torch to heat it up and also penetrating spray. There also seems to be a case of 17mm being slightly big and 16mm being too small.
This is the pipe we are doing with.

I should note we do not particularly care about reconnecting the EGR as we also were able to get a very nicely machined block off for it from the EA82 intake. But the pipe still will pose an issue. Does anyone have a secret for taking this off or possibly going another route?
